BEER-ROD.

. specification of Letters Patent.

Patented Feb. 22, 1910.

Application filed .Tune 4, 1909. Serial No. 500,155.

following is a specification.

The object is to provide in a single or 'unitary element an eduction passage for dispensing the beer or other beverage and means for supplying air for forcing purposes and for cooling the eduction passage.

To these and other ends the invention re sides in the subject-matter hereinalfter more particularly described and defined in the subjoined claims.

The annexed drawing illustrates an embodiment of the invention that has 'given excellent results in ractice.

Figure 1, is a vert1cal sectional view of the rod applied to a cask or barrel; Fig. 2, is a perspectivev view partly in section of the rod detached; and Fig. 3, is a section on line. 33 of Fig. 1.

Referring to the drawings, the numerals 1 and 2, designate concentric or nested tubular shells which may be secured relatively by rings or collars 3. The hollow rod or tube l, constitutes a passage for the liquid and the space between the tubes constitutes an lair chamber. The rod or tube 1,4 is slightly longer than the tube 2, and the projectin portion is tapered andl closed and provi ed with apertures 4, as usual, to admit uthe liquid to the dispensing rod 1.

5, indicates a bung which is carried by the rod 1, and which coperates in the well known manner with the bushing 6, on the barrel or cask tc secure a tight joint. There is an annular air space or chamber 7, in the bung which is limited by packing rings 8 and 9, whereof the ring 8, is tight to provide a perfect seal and whereof there 1s some clearance as at 10, between the ring 9, and the tube or rod 1, so as to ermitl suthcient air to escape into the cask or forcing purposes.

11, indicates, an air intake which connects with a suitable source of cold air under the desired pressure.

The annular space between the tubes or shells 1 and 2, is divided into two compartments by partitions or vanes 12 and 13, and the only means of communication between the compartments is by the ports 14, near the bottom thereof.

In practice cold air under suflicient pressure is admitted to the bung chamber 7, and some of it escapes via the annular passage 10, into thecask and tends to force the liquid through the rod. The remainder circulates around and tends to cool the liquid passage 1, by entering the inlet port 15, and passing down through onecompartment and up the other and finally escaping through an outlet or relief passage 16.

Having described the nature and objects of our invention, what we claim as new and desire to secure by Letters Patent is :V

1. A beer-rod having'a surrounding air 2. A eer vrod having a surrounding a`irjacket, and a bung carried by the rod and having an air chamber communicating with said jacket and having a separate outlet for suppl ing air for forcing purposes.

3. beer rod comprising nested tubular shells whereof the inner shell constitutes a liquid passage and whereof the space between the shells constitutes an air space, vanes dividing said space into intercommunicating compartments whereof one 1s provided with an inlet and the other wlth an outlet, and a b ung equipped withan air chamber adapted to supply air to said compartments for coolinpur oses and adapted lto `Supply air to the arre for forcing purposes, substantially as specified.

In testimony whereof we have hereunto signed our names to this specilcatlon In the presence of two subscribing witnesses.
